The original building, situated in the East Bay hills overlooking San Francisco Bay, was completed in 1942. Designed by Arthur Brown, Jr. (designer of the Coit Tower in San Francisco), the domed structure was built to house Berkeley Lab's namesake E. O. Lawrence's 184-inch cyclotron, an advanced version of his first cyclotron for which he received the Nobel Prize in Physics in 1939. Today, the expanded building houses the Advanced Light Source (ALS), a third-generation synchrotron and national user facility that attracts scientists from around the world.
